@sierdzio Firs of all thank you for your advise but I want to use only gSOAP, Also I agree with you that this has nothing to do with Qt, although I want to write this program in Qt but I can not write even in native c++ yet.

@L.Gogs If you can't write it without Qt then you should really ask on the gSOAP mailing list. Why do you think Qt forum is the right place to ask about gSOAP? If you're lucky somebody reading here will be able to help you but it is much more likely to get help in the right place...
